Hello my name is Adrien. I specialize in complex game systems, and I do have multiplayer experience.
I tend to be a generalist as I am often the only programmer or the lead programmer in the projects I have been a part of. So I have learned most if not all areas of the engine at one point or another.
I am familiar with GAS, enhanced input system, AI behavior tree, animation blueprints, UI, multiplayer replication with server side authority, and even editing materials & VFX, and so on.
I know both blueprints and especially C++.
You can check out examples of my work here.
